Why Choose Aluminium Windows?

Aluminium windows offer a host of benefits that cater to both contemporary and traditional homes:

  • Sleek Aesthetic Appeal: Known for their slim profiles, aluminium frames allow for larger panes of glass, flooding your home with natural light and offering uninterrupted views.
  • Durability and Strength: Aluminium is a robust material that resists warping, rusting, and corrosion, ensuring a longer lifespan.
  • Eco-Friendly: Aluminium is highly recyclable, making it an environmentally responsible choice.
  • Low Maintenance: Unlike wooden frames, aluminium requires minimal upkeep—just a simple clean to keep it looking new.
  • Versatility: Available in various colours, finishes, and configurations, aluminium windows suit a wide range of architectural styles.

Comparing Aluminium and uPVC Windows

1. Durability:

  • Aluminium frames are stronger and last longer than uPVC, making them ideal for larger window configurations.
  • uPVC is also highly durable and resists weathering but may not offer the same structural strength as aluminium for expansive designs.

2. Energy Efficiency:

  • Aluminium windows now incorporate thermal breaks, significantly improving insulation to rival that of uPVC.
  • uPVC windows generally offer good thermal performance but may lack the same modern aesthetic.

3. Aesthetics:

  • Aluminium frames are slimmer, creating a modern, sleek look.
  • uPVC tends to have bulkier frames, which might not suit every design preference.

4. Cost:

  • Aluminium windows are typically more expensive upfront but can offer better long-term value due to their durability and low maintenance. 
  • uPVC is a more budget-friendly option but may require more regular upkeep.

Key Features of Aluminium Windows

  • Longevity: Aluminium windows can last 30 years or more, far surpassing other materials in lifespan.
  • Customisation: Available in various colours and finishes, including powder-coated options for a long-lasting, vibrant look.
  • Energy Efficiency: Modern aluminium windows include thermal breaks and double or triple glazing to keep homes warm and reduce energy bills.
  • Security: Aluminium’s strength makes it ideal for integrating advanced locking systems, giving you peace of mind.
  • Weather Resistance: Aluminium frames have been designed to offer more resistance towards bad UK weather.

Maintenance of Aluminium Windows

One of the standout benefits of aluminium windows is their low maintenance requirements. Here’s how to keep them in pristine condition:

  • Regular Cleaning: Wipe frames with a damp cloth and mild soapy water every few months to remove dust and dirt. Avoid abrasive cleaners that could damage the finish.
  • Inspect Seals and Hinges: Check for any signs of wear or damage on seals and hinges to ensure smooth operation and optimal insulation.
  • Lubrication: Apply a small amount of silicone spray or light oil to moving parts like hinges and locks annually.
  • Corrosion Prevention: Modern aluminium windows are coated to resist corrosion, but if you live near the coast, we’d recommend opting for marine grade paint finishes for maximum protection against the harsher coastal environment. 

With these simple steps, aluminium windows will retain their sleek appearance and functionality for decades.

Customisation Options

Aluminium windows offer unparalleled flexibility when it comes to customisation:

  • Colours and Finishes: Choose from a wide range of powder-coated colours, including classic white, sleek anthracite grey, or vibrant custom shades.
  • Glass Options: Opt for double or triple glazing, tinted or frosted glass, or patterned designs for added privacy and style.
  • Hardware and Accessories: Select from a variety of handle styles, locking mechanisms, and hinges to suit your design preferences.
  • Configurations: Aluminium windows can be customised into casement, sliding, tilt-and-turn, or bay window designs, ensuring they fit any home style.

This level of customisation allows you to create a look that complements your home perfectly.

How Long Do Aluminium Windows Last?

When it comes to longevity, aluminium windows are an excellent choice. With proper care, they can last for 30 to 45 years or even longer. Their durability is due to:

  • Corrosion Resistance: Powder-coated finishes protect aluminium from rust and wear. Additionally, opting for marine-grade paint finishes can provide enhanced protection against the harsher coastal environment.
  • Structural Integrity: Aluminium is inherently strong, meaning it won’t warp or crack over time.
  • Minimal Wear: Unlike other materials, aluminium resists damage from weathering and requires only light maintenance.

By investing in aluminium windows, you’re choosing a product that will remain functional and stylish for decades.

How Much Do Aluminium Windows Cost?

The cost of aluminium windows depends on several factors, including size, style, and finish. On average:

  • Casement Windows: £400–£800 per window
  • Bay Windows: £1,200–£2,400
  • Bespoke Designs: Prices vary widely based on customisation

While aluminium windows have a higher upfront cost, their longevity, low maintenance, and aesthetic appeal often make them a worthwhile investment.
